Default Steel bolt in aluminum: anti-seize or anti-ox?

I am repairing an aluminum brake (i.e., a brake for bending aluminum house
flashing/cladding). It is made of aluminum castings and extrusions, held
together with steel bolts and screws. Every single bolt/screw is corroded
in place! Not so much rusted as bound-up by corrosion of the aluminum it's
in. AND ... all the screw are Phillips head! &!@^&%^%$&*?!

Anyhow, I WILL get the screws out and when I put it back together I will
not use Phillips heads and I will coat them. So, the question is: do I
coat them with anti-seize, or with anti-oxidant? If anti-seize, does it
matter which form?

Thanks,
Bob


Get the Aluminum filled anti-seize. If you want, put Heli-coils in all the
holes.

This site says zinc. Look down the page at the application table.
